Max Pearson presents a collection of the week’s Sporting Witness and Witness History programmes.

We hear about the half-clay, half-grass exhibition match between Rafael Nadal and Roger Federer.

Then, we look back through the archives to find out how Greece held a referendum to decide the country’s future.

Next, a mountain massacre on the Himalayas in Pakistan.

Plus, India’s coal-mine rescue.

And, how a mother successfully campaigned to change her child’s gender on official documents in Argentina.
